fn allocate_one(&self) -> Result<Frame, AllocError>

Allocates a single Frame

fn try_allocate_zeroed( &self, frame_count: usize, ) -> Result<Frame, ZeroAllocError>

🔬This is a nightly-only experimental API. (kernel_allocation_zeroing #2)

Tries to allocate a contiguous region of frame_count frames from a prezeroed buffer
